Multi-subject event-related fMRI - Repetition priming

These data sets comprise contrast images from single-subject fMRI analyses or 'first-level' analyses from the repetition priming experiment described here. In the summary statistic approach to Random Effects Analysis (RFX) these contrast images are then used in a 'second-level' analysis allowing you to make inferences about the population from which the subjects were drawn.

These contrasts are for the overall effect of faces, characterised using either (i) a canonical HRF (single con image per subject), (ii) an informed basis set (three con images per subject) and (iii) an FIR basis set (12 con images per subject).

Download the archive rfx.tar.gz and extract the contents to a new directory. The
archive contains the contrast images con_0006.img to con_0017.img, a plot
of the first-level design matrix and group fixed-effects
results (ffx_mip.jpg), and a README file. You can also
download just the README file.

We also show you how to do a nonparametric random effects analysis.
You can check the results of your analysis by downloading the archive
spm99_rfx.tar.gz for the parametric approach (SPM) and
snpm_rfx.tar.gz for the nonparametric approach (SnPM). There is
also an archive of results for a nonparametric analysis using the
`variance-smoothing' option
